Properly close test http servers in unversioned

If not, using `go test -count=n` would make them pile up and ultimately
get to the limit of open files:

	client_test.go:522: expected an error, got Get http://127.0.0.1:46070/api: dial tcp 127.0.0.1:46070: socket: too many open files

Steps to reproduce (no longer fails):

	godep go test -short -run '^$' -o test .
	./test -test.run '^TestGetSwaggerSchema' -test.count 100

Note that this might not fail if your `ulimit -n` is not low enough.
